Is there ever reward seat sales for Upper Class

I have often used Miles plus Money offers for cheap economy tickets which I've found to be fairly good value as you only need 2,000 miles.
I've now got approx. 130,000 miles so have been looking at an actual Reward seat. Economy seems a complete waste after taxes, with Premium being a little better.
I can remember various "reward seat sales" but from what I remember they have been for Economy or Premium.

Do Virgin ever have reward seat sales for Upper class?

the only one I recall was to tokyo in the months after the fukushima reactor explosion.

Sorry.

I have never seen them but have upgraded (with cash) on the manage my booking page and got some good bargins,we have got about the same as you (each)in miles and I keep wondering the best way to use them

Thanks for the replies. Just got the following answer from Virgin,
"Thank you for your enquiry.

Certainly! Upper class rewards seats can be included in sale offers.

Sale offers may be introduced later on, but unfortunately we have no prior knowledge of if or when this may be, or what the reductions may be, as this can change to reflect market conditions/competition."

Sounds promising, but I'll believe it when I see it.
